I am not unhappy being called "Aussie", which should be obvious from my user name.
I just find it incongruous that one abbreviation is acceptable, another is not. I do not know why "jap" is offensive to Japanese, not that I use the term directly to them. Abbreviations and acronyms seem to be a way of life these days, without inferring offense.
And "kiwi" for a New Zealander or "pom" for an Englishman seem to be accepted.
Certainly terms like "wog" and "chink" may be unacceptable, but there are much serious forms of racism to be concerned about than "nicknames".
End of this discussion from me, thank you.
I'll go back to my quest for extras.
Happy punting
